Thanks for all your suggestions. I created a plug-in project from the templates with an empty workspace, and it was displayed correctly. I tried to import that same project into the main linuxtools workspace, and then the bug occurs. After playing a bit with the target definition, I found the setting that makes the TMF RCP ugly:
diff --git a/lttng/org.eclipse.linuxtools.lttng.target/lttng-eStaging.target b/lttng/org.eclipse.linuxtools.lttng.target/lttng-eStaging.target index 0c478fd..3662dda 100644 --- a/lttng/org.eclipse.linuxtools.lttng.target/lttng-eStaging.target +++ b/lttng/org.eclipse.linuxtools.lttng.target/lttng-eStaging.target @@ -10,11 +10,11 @@ <location includeAllPlatforms="false" includeConfigurePhase="false" includeMode="planner" includeSource="true" type="InstallableUnit"> <unit id="org.eclipse.cdt.feature.group" version="0.0.0"/> <unit id="org.eclipse.sdk.ide" version="0.0.0"/> -<repository location="http://download.eclipse.org/releases/staging"/> +<repository location="http://download.eclipse.org/releases/kepler"/> </location> The staging repo seems incompatible, while kepler is OK (as suggested by Marc-Andre). I was not successfull at reproducing the bug only with raw SWT CTabFolder/Item (sorry Alexander). It seems that the bug occurs from within the workbench only. I tried to use gtkparasite to check the widget tree. There is only one difference for the pane widget attribute: can-focus=FALSE in the case of the correctly displayed widget, while can-focus is TRUE when the widget is not displayed correctly. But this is probably not the cause of the error... Here are some screenshots: http://secretaire.dorsal.polymtl.ca/~fgiraldeau/eclipse/bug/20140411-swt/ Thanks for all your comments.
